Defensive Compounds. All developmental stages of oedemerid beetles contain and produce cantharidin as a defensive substance. The total amount of the terpenoid anhydride increases in successive instars [306]. Moreover, by using deuterium-labelled cantharidin it was found that males of Oedemerafemorata transfer no or only very small amounts of cantharidin 48 to females during copulation. False blister beetles cause a severe dermatitis, i.e. blisters with burning and itching sensation a few hours after contact with oedemerid haemo-lymph [307]. 

Several predation tests especially with spiders and blister beetles [121,313, 314], show that spiders exhibit a wide range of sensitivities to meloid beetles as prey. In the racoon Procyon lotor it was shown that they quickly form an aversion to blister beetle prey, which is induced by cantharidin [314]. 

Insects such as blister beetles and some caterpillars can sting or bum when they are touched. Wear gloves or leam to identify common garden insects.

Blister beetles secrete cantharidin, a powerful vesicant. Crushing a blister beetle between the fingers results in severe blistering of the skin. When horses eat hay containing blister beetles, they often die from gastroenteritis and kidney failure caused by cantharidin poisoning. 

Is commonly known as Spanish fly and is derived from blister beetles. Karras speculates that it may be a more common cause of morbidify than is recognized [12]. It is used as a sexual stimulant and is an ingredient in some wart removal remedies [13]. Poisoning is noteworthy for its dramatic effect on the gastrointestinal and urinary tracts, as well as occasionally inducing cardiac abnormalities and seizures [12,13]. The patient... 

Leaves with large holes. Cause Blister beetles. These A" long, elongated beetles have yellow and black stripes. Wear gloves to handpick, since these beetles secrete a substance that may cause blisters. Blister beetle larvae help control grasshoppers, so think twice before spraying to control them. Treat plants with a commercial pyrethrin spray or dust if damage is severe. 

Handpick adult beetles into a can of soapy water or a 5 percent solution of isopropyl alcohol. Wear gloves if your pests are blister beetles contact with crushed beetles can cause bums and blisters on skin. Shake infested plants in early morning to knock beetles onto a dropcloth, then scoop them up and destroy. 

Blossoms and foliage disappear. Cause Blister beetles. These metallic, dark-colored, beetles have long antennae and long legs. They begin chewing on flowers and leaves in June. Blister beetles have body fluids that may cause painful blisters on skin contact. Handle only with gloves. Control serious infestations with pyreihrin. 

Control Usually controlled by natural enemies (blister beetle larvae, ground beetles, predatory flies, birds, parasitic nematodes, fungal dieases) cultivate fields in fall to kill overwintering eggs aerial sprays of commercial protozoan disease Nosema locmtae) may be effective over large areas but is not useful on a home-garden scale. 

Very few insects have mandibles strong enough to bite into human skin, although a few, such as the striped blister beetle, can cause skin irritation if you squash them in your hands. Likewise, few plant diseases cause corresponding human illnesses. Howes er. you can wear rubber gloves when handpicking pests if it makes you more comfonable with the job. You can also remove some types of insects with a small hand-held vacuum, while other types can be shaken off a plant onto a dropcloth.
